TIRE-WORKING TOOL.

To all whom it may concern:

Be it known that I, PASGIIALL WV. SMrrn, a citizen of the United States,and a resident of Seattle, county of King, and State of Washington, haveinvented certain new and useful Improvements in WVire-WVorking Tools, ofwhich the following is a specification.

This invention relates to wire working tools, and has for its principalobject, to provide a tool of this character which may be applied to oneend of a roll of wire, and by means of which suitable lengths of thewire may be fed beyond the cutting jaws of the tool, the length s0 fedwrapped about the intersection of two rods (such for example as rodscommonly used in the reinforcement of concrete), and the wire then tiedand cut off by the tool.

. Other objects will appear as the invention 1s more fully described inthe following specification, illustrated in the accompany- .ing drawingsand pointed out in the appended claims.

In the drawings, Figure 1 is a plan view substantially in centrallongitudinal section, with parts broken away. Fig. 2 is an edgewise viewof Fig. 1, looking in the direction of the arrow. Fig. 3 is a view, ofthe cutting end of the device partly in section. Fig. l is a fragmentaryview of two intersecting rods, showing the wire after it has been loopedaround the rods and its ends twisted together and cut off.

Referring now more particularly to the drawings, reference numeral 1designates one of the members of the device, and 2 designates the othermember. These two members are of the form as plainly shown in Fig. 1,and are pivotally joined to each other by the bolt 3, so that the twomembers have a scissors-like action. The extreme righthand ends of boththe said members are preferably circular in cross section, so as to formmore conveniently shaped handles. Both of the said members are hollow,as shown. Passing through the member 2, in the direction of its length,is the wire 4, one end of which is rolled or wound upon a spool, orcoil, in the usual manner. The free end of the wire is led in throughthe open ing 5, in the member 2, and thence along the interior of thesaid member, and passed between the lower end of the shoe 6 which ispivoted, at 7, to the small carriage 8, slidably mounted on the rod 9,which is fixed to Specification of Letters Patent.

the stud 10, projecting from the memberQ. Between the said carriage andthe stud 10 is the helical spring 11 which constantly urges the carriagetoward the free end of the rod 9.

The shank of the shoe 6 is slotted, as shown, and through the said slotprojects the pin 12, which is rigid with the member 1, so that when theright hand end,or handle, of the member 1 is moved away from the member2, about the pivot 3, the toothed face of the shoe 6 is caused to gripthe wire 1 and draw the same forward, and when the member 1 is returnedto its position as shown in Fig. 2, the said shoe rides freely backalong the wire 1, to its normal position. In this manner a quantity ofthe wire 1 equal in length to the movement of the shoe 6, may be fed outthrough the opening as shown through the screw cap 13 in the member 2,and, when the members 1 and 2 are closed, the end of the wire enters thecorresponding central opening in the similar cap 14 in the member 1.

Adjacent the central opening in the cap 13 is the cutting jaw 15, whichmay be held in place by the block 16, or in any other approved manner.

Pivotcd to the member 2, at 17 is the lever 18, the freeend of whichhasa cutting edge, as shown, which cooperates with the cutting member 15.The opposite end of the said lever may be held in the position shown inFig. 1, by means of the spring 20. Beneath the inner end of the saidlever is one end of the trigger 21, pivoted at 22 to the member 2. Theopposite end of the said trigger is pivoted at 22 to one end of thecurved link 23, which extends around throughthe member 2, and ispivotally connected, at 24-, to the shorter end of the bell-crank lever25, pivoted upon the bolt 3, so that by pressing inwardly upon the freeend of the lever the cutting edge of the lever 18 is caused to descendtoward the cutting jaw 15 to out OK the wire when desired.

Adjacent the central opening through the cap 141, in the member 1., isthe toothed block 26, which is firmly secured to the said memher, andcooperating with the said block is one end of the toothed trigger 27,pivoted, at 28. to the member 1, the spring 29 holding the said triggerin its normal or gripping position.

Beneath the longer end of the trigger 27 is one end of the lever 30,pivoted at 31, to

the member 1, and to whose shorter end is i pivotally connected one endof the link 32, the opposite end of which link is similarly connected,at 33, to the shorter end of the lever 34:. By means of this arrangementof the parts mentioned, it is clear that, when the wire is projectedthrough the central opening in the cap 13, as above fully described, theend of the wire so projected may be firmly gripped between the toothedblock 26 and the toothed end of the lever :27, and that the pressinginward of the free end of the lever 3% will regulate the opening betweenthe said block and the toothed end of the lever 27.

The operation of the device is as fol lows:The handle ends of themembers 1 and are moved apart about their pivot 3, which, of course,causes their opposite ends to more apart correspondingly and causes theend of the wire l to project through the central opening oi the cap 13,as already fully explained; the intersecting rods 33 or other suchmembers to be tied, are placed between the now spread apart curved endsof the members 1 and 2, so that the joint of the intersecting rods whichis about to be tied is in about the location indicated at A in Fig. l;the said members are now returned to their positions as seen in thedrawings, which. causes the projecting end of the wire to be caughtbetweenthe block 26 and the lever 27, as alreac y explained; the curvedends of the members 1 and 2 are now again moved apart, which, of coursedraws a considerable length. of wire through the member 2, it being keptin mind that, during the operation last described, the end of the wireit is caught between the lever 27 and the blcclr 26 of the member 1 andtherefore mores with that member as it swings about its pivot 3, andthat meanwhile the wire is free to slip through the other member. Theoperator now draws the device toward himself and in to the position asin dicated by the dotted outline in Fig. 1; the device is then turnedabout its longitudinal axis one or more turns which twist the wirefirmly around the joint to be tied, as plainly seen in Fig. i, and afterwhich the wire is cut off, as also plainly seen in that figure.

While I have shown a particular form of embodiment of my invention, I amaware that many minor changes therein will readily suggest themselves toothers skilled in the art without departing from the spirit and scope ofmy invention, and I, therefore,

, desire to avoid being limited to the exact embodiment hereinabovedescribed and shown in the accompanying drawings.

Having described my invention, what I claim as new, and desire toprotect by Letters Patent, is

1. The combination in a wire working tool, of a pair of hollow membersconnected to each. other in scissors-like relation, means forautomatically feeding the wire along one of said members when they arebeing opened with respect to each other, means on the other member forgripping one end of the wire when the members are closed with respect toeach other, and means on one of the members for cutting of]? the wire.

The combination in a wire Working tool, of a pair of hollow membersconnected to each other in scissors-like relation,-one of said membersbeing adapted to receive the wire from a wire supply, means within thelast-mentioned member which grips the wire as the members are beingopened with respect to each other, and whichrides freely along the wirewhen the said members are being moved in the opposite direction, wherebyan end of the wire is fed beyond the end of that member, means withinthe other member for gripping the projected end of the wire when themembers are closed, a pair of cutting jaws within one of said memberswhich is adapted to cutthe wire, a lever pivoted upon the pivot pin ofthe said members, and connections between the said lever and one of thesaid jaws.

23. The combination in a wire working tool, of a pair of hollow membersconnected to each other in scissors-like relation, each ofsaid membersbeing substantially semicircular at approximately one of theirrespective ends, so as to surround a joint to be tied when the saidmembers are closed with respect to each other, a wire gripping devicewithin one of the said members which is adapted to cause the feed of thewire when the said members are being opened with respect to each other,means within the other member which grips an end of the wire when thesaid members are closed and which holds that end of the wire againstmovement with the other member, so that when the saidmembers are againopened a further feed of the wire occurs, and means upon one ofthe saidmembers for cutting off the wire.
